, WINDOW SASH AND CURTAIN OPERATING MECHANISM.

Specification of Letters Patent.

Application filed October 25, 1917. Serial N 0 198,447.

To all whom it may concern.

Be it known that I, HENRY W. ScJaWARZ, a citizen of'the United States, residlng at art, 1n the county of McLennan, State of Texas, have invented certain new and useful Improvements in Window Sash and Curtain Operating Mechanism; and I do hereby declare the. following to be a full, clear, and exact description of the invention, such "as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to Window structure, and has particular reference to combi nation window sash operating devices and window protecting mechanisms.

The object of the invention is to construct a Window structure which embodies, in ad dition to the usual sashes, a shade, screen and curtain combination, together with actuating the various parts of the combination, the various elements forming parts of a built-inorganization which is therefore, in the main, shielded from View in the window frame.

A further object of the invention is to associate with the window sash operatin alarm which will be automatlcally sounded when the sashes are opened after the alarm mechanism has been set to operative position. 7

With the above objects in view, andsuch others relating to the details of construction as may hereinafter appear, my invention will now be fully set forth and described ref erence being ha to the accompanying rawings.

In the drawings Figure 1 is a front elevation of a window frame,

Fig. 2 is an elevation showing the window casing facing removed,

Fig. 3 is a verticalsection on line 3 3 of Fig. 2, a

Fig. 4 is a section on line H of Fig. '2, Fig. 5 is a sectionon line 55 of Fig. 2, Fig. 6 is a detail view of an alarm mechams-m,

Fig. 7 is a vertical section showing a modification and Fig. 8 is a longitudinal section, in detail, of a clutch. 7

Referring more particularly to the drawings, 1 represents the stiles and 2 the cross pieces of the window frame, the stiles slidably carrying the upper and lower sashes 3 and 4 respectively. Extending through the stiles, transversely of the frame and at a height whlch approximates the meeting are disposed of the sashes Shaft 5, the 1 ered.

The ends of tical chambers casing, and

the shaft extend into the verat each side of the window upon one side open the sashes, it is necessary to lock them in open position by the engagement of the pawl 12 with the teeth of the ratchet disk 11. The shaft 9 is also intended for use in operating a combination screen, shade and shield mechanism. For this reason, the bevel gear 7 is slidable on the shaft 5, so that clutch elements 16 upon'its inner face may be carried into and out of engagement with the corresponding clutch elements 17 7 upon the opposing face of the drum 13. 18 normally throws the gear 7 away from the drum 13, and in order to permit the'advance of the gear toward the drum the teeth of the former are elongated, and the pinion 8 is movable with relation to the gear 7 by reason of a sliding action of the crank shaft 9 against the normal 19 to throw the shaft 9 inwardly. Thus, by drawing the shaft 9 toward the operator, pinion 8 cam against the the teeth of the extended teeth of the gear 7 and throw the Patented Feb. 4, 1919.

" nected by clutch elements 17 after which the rotation of the sha operate the sashes.

ments are disengaged, a further locking device to 13 when the sashes are open.

and 16 into engagement, ft 9 will it is necessary to have hold the drums For this pur- I pose, a pair of levers 20 are pivotally mount- 21 being directed to prevent the rotation of the drums under the action of the springs 15.

As a means to warn the occupants of the house of burglarious attempts to enter the window, I have mounted a plunger 22 within a casing formed by guides 23 upon the inner face of the casing, the upper end of the plunger carrying a clapper 24 which may strike against a bell 25 to sound an alarm. Extending through the facing of the casing and pivoted to rock with relation thereto, is a pair of links 26'whose outer ends pivotally engage the plunger 22. The inner ends of the links are transversely cona bar or pin 27 which stands in the path of movement of the teeth 27 formed upon the flange of the corresponding drum 13, so that as said teeth strike the pin 27 the links 26 are rocked to reciprocate the plunger and sound the bell. A' guide in 28 extends through the guides 23 and also through an arcuate slot 29 in the plunger 22, and the action of the teeth 27' is against the influence of the action of the spring 30 to determine the operative or inoperative position of the alarm, the clapper 24: is carried by a crank arm vertically pivoted in the upper end of the plunger 22 so that the clapper may be swung away from aposition where it will contact the bell into an inactive position.

As a modified form of the means for holding the windows in whatever position of adjustment they may be caused to assume, a crank 5 may be bent into the shaft 5 at each side of the frame, and may have attached thereto as shown in Fig. 7 the end of a spring 15, these springs tending to hold the cranks 5 downwardly below the shaft. Thereby, the rotation of the latter is prevented against any except a positive rotative influence. 4

Extending across the upper end of the casing, above the window opening is a roller 31 which parallels a take-up roller 32 which extends below the window opening. Within an inclosed framing which is built outside of the window casing there is also provided a third roller 33, which normally holds a continuous length of screening 34, a length of shade material 35 and a flexible shield or metal curtain structure 36. The roller 31 \Nhen the clutch ele-- has its bearing shaft extended so that there can be fixed thereon a sprocket wheel 37 around which is passed a sprocket chain 38 whose opposite end passes over a series of sprocket teeth formed on the hub of the bevel gear 7 Again, the bevel gear 7 has a second set of sprocket teeth which receives a chain 39, whose opposite end passes over a sprocket wheel 4:0 fixed upon the shaft of the lower roller 33. Thus, the actuation of the bevel gear 7 also causes the rotation of the rollers 31 and 33 to extend the elements of the combination flexible strip. The upper roller 31 is provided with a winding spring ll which tends to return the flexible strip to the upper end of the window casing,and a sprocket chain 12 which passes 7 over suitable sprocket wheels 43 and 4 1 on the roller 31 and the roller 33 respectively actuates the latter so that the strip is wound thereon when the rollers are released by the lifting of the pawl 12 from the ratchet disk 11.

It will be primarily noted from the foregoing description that all of the parts of the mechanism are controlled from a single operating device, and that the flexible strip may be actuated either in combination with the sashes, or may be adjusted independently of the latter. The elements of the flexible strip operate across the outside of the window opening, within suitable vertlcal guide-ways, and, in accordance with the Weather conditions or other governing circumstances, the screen, theshade or the metal shield structure may be extended across the window opening. Furthermore, the metal shield structure may serve'as an awning or a fire shield.

It will be apparent-from the foregoing description that I have provided a complete and effective window sash operating mechanism and protecting devices, whose selective relationship, and unitary control render it possible to meet the various conditions of weather and other circumstances.

WVhat I claim as my invention is 1. In a window structure, upper and lower sashes, a shaft extending across the structure between the sashes, pinions upon the shaft, rack bars carried by the sashes and meshing with the pinions, rollers mounted at the top and bottom of the'window structure, a flexible strip operative over the rollers, operating connections extending from the shaft to said rollers, and means for OPGI! ting the shaft to actuate the sashes and also to actuate the rollers.

2.
